Setting LedgerDimension field on LedgerJournalTrans table in AX 2012 via X++ code

The following code can be used to update LedgerDimension field on the LedgerJournalTrans

 RecId getDimension(str _ledgerAccount, str _businessUnit, str _costCentre, str _jurisdiction, str _subscriberType)  
 {  
   DimensionServiceProvider      DimensionServiceProvider = new DimensionServiceProvider();  
   LedgerAccountContract        LedgerAccountContract = new LedgerAccountContract();  
   DimensionAttributeValueContract   ValueContract;  
   List                ListValueContract = new List(Types::Class);  
   dimensionAttributeValueCombination dimensionAttributeValueCombination;  
   DimensionStorage          dimStorage;  
   if (_businessUnit)  
   {  
     ValueContract = new DimensionAttributeValueContract();  
     ValueContract.parmName('BusinessUnit') ;  
     ValueContract.parmValue(_businessUnit);  
     ListValueContract.addEnd(ValueContract);  
   }  
   if (_costCentre)  
   {  
     ValueContract = new DimensionAttributeValueContract();  
     ValueContract.parmName('CostCentre') ;  
     ValueContract.parmValue(_costCentre);  
     ListValueContract.addEnd(ValueContract);  
   }  
   if (_jurisdiction)  
   {  
     ValueContract = new DimensionAttributeValueContract();  
     ValueContract.parmName('Jurisdiction') ;  
     ValueContract.parmValue(_jurisdiction);  
   }  
   if (_subscriberType)  
   {  
     ValueContract = new DimensionAttributeValueContract();  
     ValueContract.parmName('SubscriberType') ;  
     ValueContract.parmValue(_subscriberType);  
     ListValueContract.addEnd(ValueContract);  
   }  
   LedgerAccountContract.parmMainAccount(_ledgerAccount);  
   LedgerAccountContract.parmValues(ListValueContract);  
   dimStorage = DimensionServiceProvider::buildDimensionStorageForLedgerAccount(LedgerAccountContract);  
   dimensionAttributeValueCombination = DimensionAttributeValueCombination::find(dimStorage.save());  
   return dimensionAttributeValueCombination.RecId;  
 }
